Arts and Crafts Trinket Box

I have this trinket box in the arts and crafts style made with a glass box and lid with pewter decoration .When I look at the bottom of the box it’s looks to have been ground out a bit , not like the polished mark on whitefriars or Dartington glass .This is much bigger if you can make out in photo .At the center there’s a circle mark about inch and half across looks like something has been smoothed out .Would this have been hand blown perhaps never saw this before.

Can't say I have seen a glass and metal arts and crafts style box quite like this. Something about it says Continental rather than English or American. I do think the bottom to be a ground pontil mark. Can't tell if the stones are real or not from these photos.

Somewhere in our loft I have an old catalogue for this hobby. (UK)It has all the bits you can buy, including the pottery roundels, sheets of metal and tools for embellishing anything you want. If I remember correctly, the jewellery bits as well. It was a very popular hobby. How good a piece was depended upon the skills,imagination and artistry of the hobbyist. See it on glass a lot here in France.

Don’t think the stones are real sounds like it could be European have seen the metal boxes but I have never seen such a large ground Pontic mark .Could have been a satin glass box and then the pewter and stones added will have a look thank you for looking.
